使用C＃从IP Camera获取图像

问题描述

Hello buddy

目前我正在开展与IP Camera（Bosch）相关的项目。我可以使用带有IP地址的网络浏览器访问相机（例如：http：//10.64.91.48）。现在我想在窗口窗体上显示视频。在互联网上多次搜索并使用下面的代码，但我面临ArgumentException，仍然无法解决它。我尝试从响应（resp.ContentType）获取内容类型，它显示text / html。

你能帮我解决这个问题吗？任何反馈都将非常感激！

Hello buddy
Currently i am working on a project related to IP Camera (Bosch). I can access the camera using web browser with ip address (ex: http://10.64.91.48). Now i want to display the video on a Window Form. Searching on the internet many times and using below code but i face an ArgumentException, and still can't resolve it. I try to get the content type from response (resp.ContentType), it show me text/html.
Could you please help me to resolve this issue? Any feedback will be very appreciated!

string CameraUrl = this.txt_URL.Text;
            if (string.IsNullOrEmpty(CameraUrl) == false)
            {
                byte [] buffer=new byte[300000];
                int read, total = 0;
                //Create a HTTP Request
                HttpWebRequest req = (HttpWebRequest)WebRequest.Create(CameraUrl);
                //Request Credential
                req.Credentials = new NetworkCredential("user", "user");
                //Get Response
                WebResponse resp = req.GetResponse();               
                //Get Response Stream
                Stream stream = resp.GetResponseStream();
                //Read data from stream
                while ((read = stream.Read(buffer, total, 1000)) != 0)
                {
                    total += read;
                }
                //Get Bitmap
                MemoryStream memstream = new MemoryStream(buffer, 0, total);
               
                Bitmap img = (Bitmap)Bitmap.FromStream(memstream); // Exception here
                this.pictureBox1.Image = img;
            }
